BRICK.

SPECIFICATION forming part of Letters Patent No. 628,799, dated J uly 11, 1899.

Application filed March 13, 1899. Serial No. 708,887. (No model.)

f0 aZZ whom. it may concern: a I

Be it known that 1, WILLIAM M. HAZEL, a citizen of the United States, residing-at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Brick, of which the following is a specification.

This invention relates to bricks; and the object thereof is to so form a brick as to tie a wall in such a manner that when it is set with mortar or cement in a wall, arch, or other structure each brick will be so connected to the other that the Wall or masonry cannot crack or settle or cannot spread or bulge apart in cross-section, which is now common in imperfectly-laid structures of bricksof the common type.

The brick constituting the subject-matter of this application maybe manufactured from clay, cement, artificial stone, or any other suitable material that can be pressed into shape by hand-press or hydraulic pressure, or it can be otherwise formed as convenience or economy may suggest.

With these ends in View the invention consists in the novel combination of elements and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

To enable others to understand theinvention, I have illustrated the preferred embodiment thereof in the accompanying drawings, forminga part of this specification, and in which- Figure 1 is a perspective View of a brick eonst ructed in accordance with my invention. Fig. 2 is a longitudinal section of the brick, the section-line intersecting the wedge-shaped pockets. Fig. 3 is a side elevation of a portion of a structure or masonry built up of bricks constructed in accordance with my invention and with parts in longitudinal section to show the peculiar relation of the pock- Fig. 4 is a perspective View of a modification of the brick. Fig. 5 is a view similar to Fig. 1, with a portion of the brick cut away to show more clearly the wedge-shaped bottom of the depressions therein.

Similar characters denote like and correg parts in each of the several figures k wings.

Ref tang to the drawings and more especially to Figs. 1, 2, and 3, Bdenotes the brick in its preferred form, and it will be seen upon inspection of Fig. 2 that it has pockets or depressions 2 formed, respectively, in its opposite faces and two pockets being located at each side of the middle of said brick. These pockets are adapted to receive the mortar or cementwhich unites the bricks to form the desired structure.

Referring again to Fig. 2, it will be observed that the pockets or depressions 2 are of wedge shape, and they are deepest at the ends of the brick. It will be also evident that the wedge portions or bottoms 3 of the pockets are sloped or inclined oppositely, and the ends 4 of the pockets are disposed approximately at right angles to the bottoms of said pockets.

When the bricks are laid upon one another in the familiar manner, the wedge pockets or depressions upon the under surface of one layer of brickswill, be opposite or directly over the wedge pockets or depressions upon the next adjacent lowerlayer of bricks, as indicated in Fig. 3, thereby forming substantially rectangular chambers or seats, in which the mortar or cement can be forced as the bricks are laid.

The peculiarity of the construction set forth will be obvious at once upon an inspection of Fig. 3, which shows the bricks assembled, and the latter are held strongly against spreading or cracking by the mortar or cement which lies in the wedge-shaped cooperating depressions or pockets in the superposed bricks. The cement is intended to fill the space bounded by the walls of a cooperating compartment, as well as between the edges and center of brick, and when dry the bricks will be suspended by the angle the mortar assumes when at rest, as will be evident upon an inspection of Fig. 3, thus causing each brick when subjected to strain to pull against another and to be also held in its positionby the resistance of the brick in the rear of its length because foo By the construction set forth I maintain a uniform thickness of the brick at its center and at its sides and ends, as shown in Figs. 1 and 4, thereby assuring more thorough adhesiveness and security from lateral movement when the mortarsets, and by forming the depressions wedge-shaped in their bottoms the mortar will readily slide down the inclined surface and will also permit the bricks to be more easily removed from the molds after their formation.

In Fig. 4 I have represented a modified form of the brick, wherein two pockets are located at opposite sides of the middle line of the brick upon its opposing faces, and this formation is advantageous in constructing small houses wherein laying the bricks the mortar is not always spread over the entire top of the brick, but the edges are simply buttered. In such a case as this the small depressions, being near the outside of the wall, catch the mortar that is used during the buttering process,whereby the same advantages are seen red.

From the preceding description it will be evident that my invention includes, broadly, not only a brick or building-block having a wedge-shaped pocket or depression, but a structure composed of such bricks and two adjacent bricks having contiguous pockets of the character specified and the angular faces of which are disposed in opposite directions.

Changes in the form, proportion, size, and the minor details of construction Within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus described the invention, what I claim is- 5 1. A brick provided on opposite sides of its l transverse medial line with wedge-shaped depressions, the bottoms of said depressions inclining down ward toward the ends of the brick.

2. A brick provided in its upper and lower faces on opposite sides of the medial transverse line with wedge-shaped depressions, the bottoms of all the depressions inclining from the said medial line inward toward the ends of the brick.

3. A brick provided with wedge-shaped depressions in its upper and lower faces on opposite sides of the medial transverse line, the bottoms of said depressions merging at their inner ends into the faces of the brick and the end walls of the same being approximately at right angles to the bottoms.

4. In a brick structure, the combination of bricks arranged to break joint and having their adjacent opposed faces provided with wedge-shaped depressions, the bottoms of the depressions in the opposing bricks being inclined in opposite directions whereby when said depressions are filled with mortaracore is formed acting toward the ends of both bricks.

5. A brick having wedge-shaped depressions in its opposite faces and arranged in pairs at its opposite ends, the bottoms of the depressions at one end of the brick being inclined opposite to those of the depressions in the other end of the brick respectively upon both faces thereof.

In testimony that I claim the foregoing as my own I have hereto-affixed my signature in the presence of two witnesses.

XVILLIAM M. HAZEL.
